To-all @07mm it may concern Be 1t known that I, THOMAS CARROLL, al citlzen of the United States, residing at Dayton, in the county of Montgomery and State totals in which the machine is not reset to zero after the total printing' but the subtotal amount remains registered in themachine in condition to have the succeeding registrations added thereto; and accompanying these features are certain locking devices .and a novel paper feeding mechanism which form an advantageous accompaniment to the fulfilment of the above mentioned objects.

With these and incidental objects in vieu the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims and a. preferred form of embodiment of which is hereinafter specifically described with reference to the drawings which accompany and form part of this specification.

In many of the figures certain of the parte which ordinarily should be represented have nevertheless been l'omitted for the sakeof clearness. L

. 'For the purpose of givingan outline of the general operation of the machine, it may A be stated that there is a series of amount keys, a series of clerks numeral keys and a series of specialtransacton keys, which when depressed set certain parts for the necessary operation of registeringg'recording and indicating, the completion of the operation ofthe machine being. e'ected by the `revolution ofthe crank handle or other suitable-means. l

The operation of the amount keys results in the setting of certain registering bars or segments to differential positions and upon the subsequent operation of the crank handle 7these segments are restored to normal position, and upon such restoration to normal position the totalizer is actuated and the printing wheels are set by means of certain intermediate connections which serve to tered upon the totalizer, a special total-key is provided which is adjusted into two different positions, in one of which when the key is subsequently depressed, the machine is prepared to print the total of all the amounts registered up to that point but the operation of the machine results in the so called clearing of the machine, that is, results in the machine being reset to Zero automatically; whereas when the total key is adjusted to its other position and then depressed, the operation of the machine results in the )rinting of the total of all the amounts registered up to that time, but this accumulation of amounts is retained upon the totalizer, that is, in eect this total is carried forward so as to have the 'succeeding amounts added to it. For convenience in designation, the total in which the machine is cleared or reset to zero will be called the final total, and the total which is printed when the machine is not cleared to zero but when the accumulation is retained upon the counter,l will be designated as I the subtotal n. y I

In order to print the various items of the special. transactions in a column separate from thatvof the cash transactions thedetail strip is mounted upon a shifting printing .c carriage and theoperation of any one of the special keys serves to set parts such that upon the subsequent operation of the main crank handle the detail strip carriage will be shifted laterally so as to eect lthe printing of these items in a different column; and the feed of vthis detail strip is arranged' so ythat whereas on all individual transactions the paper is spaced the sameincrement of distance at eachoperation, yet upon the printing of the totals the paper is givenv a ldouble spacin movement so as easily to enable the identi cation of these totals on the detail strip.

The general vconstruction off-certain of the features herein set forth,l such forV example as the registering segments and their operating devices, the indicator mechanism, and

the detail stripcarriage shiftingy devices, is i A35 (see power of the machine and edects a rotation nioaeeo practically the same as that described in a co-pending application Serial No. 270,786, filed by Thomas Carroll on July' 22, 1905.

1With the above general description of the operation of the machine, the specic parts thereof will now be described more in detail. s

Referring to Figs. 1, 2- and i it will be seen that there are three 'different groups of keys,

the amount keys 3U, the two banks of clerks numerals keys 31 permitting the recording of clerksv numerals from 1-99, and the three special transaction keys 32, and then there is be later described. The exact arrangement of the keyboard is best shown in Fig. 4,in which figure the key stems are shown sectionalized, the ordinary heads or buttons for showing` the designation of the key being shown in the other figures. A crank handle JFig. 12) supplies the main actuating of the two main operating shafts by means of the gearing shown in said figure, the handle 35 being fast to a gear wheel 36 which meshes with a larger gear wheel 37 mounted upon the outer end of the upper operating shaft 38, and the gear 37 in turn. meshes with a companion gear wheel 39 fast upon the outer end of the lower operating shaft 4&0, these two shafts 38 and 40 being provided with the various operating cams and devices for actuating the dierent parts of the machine. liast upon the shaft 38 is another gear wheel 4:1 which meshes with a smaller gear wheel 42 which is splined upon the right hand end of an auxiliary operating shaft 43 which elfects the shifting of the printer carriage in the manner to be described. i

@parenting @lamenta-The operation of the operating elements'by the keys will now be described. The keys are provided with springs 47 which normally hold the keys in outward position by pressing against stop pins 48. Extending across the lower portion of the machine is a transverse shaft 49 upon which arepivoted the various registeroperating segments 50, the exact contour of which segments is shown in detail in Fig.

14. The upper ends of these segments are formed with teeth 51 which mesh with pin- Qions 52 (see Fig. 1) mounted loosely upon the transverse shaft 53, and by means of certain idle pinions later to be described,

these-pinions 52 are arranged to be coupled to the totalizer wheels so as 'to transmit to the totalizer the various differential movenA ents of the register operating segments 50. There is one of these operating segments 50 for each of the banks of amount keys as shown in Figs. 1 and 4, but lfor the bank of clerks numerals keys the teeth on the end of their operating elements are omitted since these elements do not operate totalizer wheels but simply serve to set printer wheels in a manner to be described; and for the .with each of the aforesaid operating elements 50 and 50a is an indicator and printer `setting segment 54 (see Figs. 1 and 2) which is pivoted upon the transverse shaft 49 but at its pivotal .point is formed with a slot as shown in Fig. 2 to permit the raising of these auxiliary setting segments for a purpose to be presently described. The forward sides of the various operating elements 50 and 502L are formed with steps'56 (see Fig. 14) which are engaged by the pins 48 of the various keys so that upon the pressing in of any key the corresponding operating element 50 will be rocked to a greater or less extent according to the value of the key depressed, the uppermost key of any bank `giving the least extent of movement to the operative element, and the lowermostkey giving the greatest extent of movement, .these differential movements being such as to effect the necessary gradations of value from 1 9, or in the ease of the special transaction and totalizing keys to give the necessary gradations of movement to permit the setting of the printing and indicating wheels to different positions. All of the operating elements are normally springpressed into their forward positions by means of springs 56l (see Figs. 1 and 4) surrounding collars mounted on the transverse shaft 49 and engaging the lower and rearwardly projecting ends of the operating eleni ents 50 and 50a. On the upper end of each of the auxiliary operating segments 54 are formed teeth 57 which are arranged toengage teeth 58 (see Figs. 13 and 14) formed on a block 59 fast upon the side of each one of the operating elements 50` and 50a. In order to raise the auxiliary operating segments 54 into mesh with the aforesaid teeth'58, there is provided a transversely extendingrestoring bar G4 (see Figs. 1, 2 :1nd 15) which extends through slots 65 formed in the segments 54.V This bar 64 forms a transverse connecting bar for two side Iplates 500 of a restoring frame which is pivoted upon the shaft 49, and the entire restoring frame including the bar '64 is lifted and rocked forward at each operation of the machine by means of the following mechanism operated from the lower operating shaft 40. Adjacent Ato each of the side plates 500 is a plate 501 which is secured to the rock shaft 49. These plates are provided with cam grooves 502 into which project pins 503 extending from the side plates 500. Y Secured to the rock shaft 49 and extending upwardly therefrom 4is an arm 504 (see Fig. 16) ,fthe upper end of which is connected to the forward end of a link 505, the rearward end of .which is forked so as to straddle the shaft 40 and near the rear end of the link 505 is an anti-friction roller 506 which projects into a cam groove 507 formed in a disk 50S secured to the shaft 40. The shape of the groove 507 is such that at the beginning of the operation of the machine it will draw the link 505 rearwardly and thereby rock the shaft 49 clockwise, by which movement the. frame comprising the plates 500 and the transverse'rod G4 will be elevated by the cam plates 501 which engage with the rollers 503. This elevation of the rod G4 will carry the auxiliary operating segments 54 upwardly so that the teeth 5T formed thereon will engage with the teeth58 formed upon the blocks 59 secured to the main operating elements 50 and 50,

this elevation of the auxiliary operating elements being permitted by slots 509 formed in the lower end of said segments and through which the shaft 49 extends, while the lower end of the side plates 500 are cut away so as to permit the elevation of the frame of'which the side plates 50() are a part. Immediately after the engagement of the segments 54 with the operating .elements 50 and 50a, the frame comurisin.nr the side arms 500 and the rod 64 isA rocked counter clockwise about. the shaft 49 by a link 510, the forward end of which f is secured to one of the plates 500, while the rearward end is forked so as to straddle the shaft 40. An anti-friction roller 511 projects from the rear end of link 510 into a cam Groove 51:2 formed in a disk 513 secured. to the shaft 40.

'l` he lower and rearward lportion of each of the operating elements 50 and 502l is formed with a projection 75 w-hich lies in the path of the restoring har 64. In the operation of these various parts, the desired keys are first pressed in whereupon the operating elements 50 and 50 are set differentially.A and then upon the operation of the machine the restoring bar 64 is first lifted so as to carry allof the auxiliary segments into mesh .with the teeth 58 of their respective operatingelements 50 and 50 so Aas to lock these two sets of elements togetherq ano then the resto-ring bar is moved forward and striking the projection 75 restores all of the operating elements 50 and 50a to normal forward position, thereby giving them differential movements of restoration, corresponding to the Vamount of their initial, displacements, and since the auxiliary segments 54 are during this period locked tc the elements 50 and 50 these auxiliary segments vare also given correspondingdegrees llfl of diiferential'movement for the purpose of setting the printing wheels and the indi: cator wheels, in a manner to be described.

The lower and rearward portion of 'each of the operating elements 50 and 501"1 is formed with a projection 75 which lies in the ing elements 50 and 50a to normal forward position, thereby giving them diderential movements of restoration corresponding to the amount of their initial displacements, and since the auxiliary segments 54 are during this period locked to the elements 50 and 50a these auxiliary segments are also given corresponding degrees of differential move-A- ment for the purpose of setting the printing wheels and the indicator wheels, in a manner to be described.

vThe depressed keys are released at the beginning of the operation of the machine by the mechanism shown in Fig. 17vwhich is operated as follows: All ofthe key bands havev detents similar to the detentf242 which coperates with the special keys, as shown in Fig. 8, with the exception that none of the slots of the remaining detents are provided with full stroke devices 240. Each of these detents has extending rearwardly therefrom a projection 514 which is provided with a `pin 515 that plays in the slot 516 formed yin the forward end of an arm 517 secured to the shaft 114. Secured to the shaft 114 and extending upwardly therefrom is an arm 518 which is connected at its upper end to thevforward end of a link 519, the rearward end oftheV latter being provided with an elongated slot 520't-hrough which extends 'an operating/shaft 38. The extreme rearward end of the link 519 is provided with an anti-friction roller 521 with which a cam disk 522 is arranged to engage at the very beginning of the operation of the machine and move the link 519 rearwardly, which movement will rock the shaft 114 clockwise and by the lower walls of the slots 516 formed in the arms 517 engaging with the pins 515 will elevate the detents 24:2 andthereby release the'depressed keys. After the printing wheels have been setl in this mannerthe printing is effected and then upon thecontinued movement of the operating. mechanism Athe restoring bar 64 is droppedto' normal position'thereby freeing 'the segments 54fro the operating elements incensoV7 y 50 and 50 and the bar 64 is then restored to normal rearward posit-ion thus carrying the segments 54 also back to normal rearward position. y

The mechanism for setting the indicators according to the keys operated comprises an arm 7 9 (see Fig. 1) extending rearwardly from each segment 54 to which arm is connected a link 80 which is pivoted at 81 to a power application bar 82 which at its rearward end is pivoted to another link 83 attached to the rearward end of a bell crank formed indicator setting segment 84 which segment meshes with a pinion 85 fast on the side of the indicator S6. To the middle portion of each bar 82 is pivoted a downwardly extending bar 93 which extends into slots formed in a cross bar 94. These bars 93 are formed with slots 95 and surround the lower operating shaft 40 and by means of cams 97 and 99 acting upon antifriction rollers 96 and 98, said cams being mounted rigidly upon the shaft 40, the indicators are set at each operation of the machine to the proper posit-ions corresponding to the keys depressed, this settingof the indicators being .effected through the power application bar This indicator setting mechanism forms the subject matter of claims 1n the said copending application and will not beV describedmore in detail here.

ln order to set the type wheels to posi Y tions corresponding to 'the keys depressed, each of the segments 54 (see Fig. 1), is provided with an antifriction roller 100 which projects into a curved slot 101 formed in an arm 102 fast upon the end of a suitable collar arranged to transmit movement to the printing wheels. This series of nested collars or sleeves 103 extend through to the left hand side of the machinebeing also shown in Figs. 2 and 11. As shown in Fig. 11, these sleeves 103 are made fast to corresponding segments 104 which mesh with pinions 105 fast upon the ends of a second series of nested sleeves 106 to which sleeves the printing wheels'107 (see Fig. 3) are made fast, these printing wheels being provided with duplicate type on their periphery for the purpose of printing both a detail strip and a check. The detailed construction for printing both the detail strip and check is set forth in said co-pending application and only so'much of the same will be described herein as to point out the novel features claimed inthe present application.

It will be seen that the setting of the printing wheels takes place upon the previously described restoring of the operating segments to normal position, during which time the segments 54 are coupled thereto and consequently the differential movements of the segments 54 act through the curved arms 102to set the printer wheels to corresponding degrees. The backward movement of the segments 54 is in each case limited by 121 mounted on the side of the totalizing.

wheels 122. The registering segments 50 normally operate the pinions 52 during the setting movements of the segments 50 but of course do not have any effect upon the totalizer operating pinions 120. However, a set of idle pinions 123 (see Figs. 1 and 2) is provided for coupling together the two sets of pinions 52 and 120, these idle pinions being mounted upon a rod 124, which rod is carried upon arms extending upward from a rock shaft- 125. This shaft is normally :l rocked at each operation of the machine to carry the idle pinions into engagement with their corresponding pairs of pinions, rthe mechanism for effecting this being shown in Figs. 2 and 6. Fast upon the upper operating shaft. 38 is an operating disk 126 formed with a cam groove'120a into which projects a roller 127 fast upon the rearwardly eX- tending arm of a bell crank lever 128. The lower end of the other arm of this bell crank lever has upon it a pin 129 (see Fig. 6) arranged to be engaged by a slot 130 formed in the lower side of the rearward i arm of another bell crank lever 131 which is pivoted at 132 to the forwardly and downwardly extending arm 133 of a threepronged piece in the upper arm of which is mounted the aforesaid rod 124 carrying the idle pinions 123, the shape of this threepronged piece being shown in detail in Fig. 6C, and the shape of the bell crank lever 131 being shown in Fig. 6b. ln Fig. 2 the notch 1130 is shown engaging the pin 120, and in such position it will be seen that upon the revolution of the upper operating shaft 38 in the direction shown by the arrow, the shape of the cam groove 126a is such thatv the bell crank lever 128 will have its downward arm rocked rearward thereby pulling rearward the arm 133 of the aforesaid threepronged device and thus the upper arm of the latter will be rocked forward to carry the various idle pinions into engagement with their respective pairs of pinions; and at the completion of the revolution of the shaft 38 the pin 134 (Fig. 2) mounted on the side of the disk 126 strikes the rearwardly extendingarin 135 of the aforesaid t three-pronged device and positively forces the' idle pinions 123 out of engagement with their respective pinions. A spring 131 norbeing formed with beveled portions so thatV when any one of the keys 32 is pressed in-v ward its pin 48 will act u on the beveled portion and then" pass. down into the slot and in so doing will force the detent plate 140 downward, and the upper end ofthe plate is formed with a rearward extending arm 142 which stands over a pin 143 formed on the forward end of the bell crank lever 131, and

vwhen any special key is pressed inward as shown in Fig. 6, the arm 142 acting upon the pin 143 rocks the bell crank lever 131 upward so as to withdraw the slot 130 from engagement with the pin 129; and this movement is sufficient to carry another slot 144 (see Fig. Gb) formed in said bell crank lever 131 on the opposite'side from the slot 130, into engagement with a pin 145 fast upon a stationary arm 146 (see Fig. extending froin the shaft 38 to the shaft 125. In this osition it will be seen that the operL ation o the cam disk 126, although having a rocking effect on the lower end of the bell crank lever 128, yet has no effect to rock forward the idle pinions 123 in the ordinary manner, since the slot 130 is no longer in engagement with the pin 129, and moreover during such period theshaft 125 and the idle pinions 123 are held secure from rocking movement because of the engagement of the slot 144 with the pin 145. It will be observed that in this manner the totalizer is thrown out of operation upon the depression of any one of the special keys, since the failure to rock in the idle or coupling pinions f 123 prevents the movement of the gear wheels 52 from being transmitted to the totalizer operating gear wheels 120. rlhis same throwout mechanism is utilized in connection with the printing of the totals. upon the operation of thel tctalizing key 33 in a manner which will be set -forth hereinafter.

Transfer mec/anisiii-. Thetransfer mechanisin is best shown in Figs. 1 and 2.

Mounted upon each totalizing wheel is a ransfer tripping pin 200 which upon the turning of the wheel from nine to Zero trlps a tripping pawl 201 against the tension of its spring 202 and thereby withdraws a shoulder 203 of said tripping pawl from under a lug 204 which projects laterally from a transfer pawl 205 of the wheel-of the next higher order, which transfer pawl is pivoted at the upper end of a transfer keys `of the lock (see Fig.

lever 206 pivoted upon a transverse rod 207 and carrying at its lower end a roller 208 projecting into a cam groove 209 formed in a disk 210 fast upon the upper operating shaft 38. There is a series of these transfer pawls and operating disks for each-one of. the totalizing wheels above the units wheel, and these pawls yare normally held in the position shown in Fig. 2'rl with their lugs 205 resting upon the shoulders 203 of the tripping pawls 201, in such manner that the forward ends of the transfer pawls are held free trom the transfer ratchetwheels 211 (see Fig. 1) which are tast upon the sides of the totalizing wheels; but when the tripping pa'wl is tripped in the manner above mentioned, the transfer pawl drops into engagement with the ratchet wheel 211 and upon the operation ot the shaft 38 in the direction shown by the arrows, the transfer awls areV all forced forward and those which have been allowed to drop down .into engagement with their' respective ratchet wheels transmit a unitary transfer movefnent to the totalizer wheels. ln the normal raised positions or' the transfer awls 205, the pawls are tree from the totalizing wheels andthe wheels can therefore be reset to Zero without the necessity of rocking the transferpawls out ot engagement therewith, this resetting to zero being part of the process of printing totals as will be later described. Retaining pawls 212 (see Fig. 1) hold the registeringwheels in proper position', but permit the turning of the4 wheels in, either direction.

Total @wattage-ln the process of printing the so-,called final totals and sub totals it may be stated that the totalizing key is arranged Vto be rotated or adjusted into one or the other of two different positions, in`

one of which positions when depressed the key prepares the parts for printing a inal total lupon the operation of the machine, that is, where Vthe totalizer is automatically reset to zero, and in the other of which positions whengthe key is depressed the subtotal is printed, the accumulated'amounty bethe totalizer; but prior to the voperation f this totalizing `key itis necessary to operate a manipulative device consisting in the present instance of an ordinary key lock, the when rotated by its key effects the unlocking ofthe totalizing key and locks all ot the amount keys and the special transaction and also sets the necessary devices for cooperating to print the desired totals. This manipulative device just referred to is shown in Figs. 4, 45 and 4". The barrel 150 the usual lslot `151 into which an ordinary formof-key is inserted, and when the key iirota'ted the rotation of the barrel carries 55 with it a stud 152 fast thereon,

which. stud faces of the s uare key shank,

' left handcorner.

.are all of such thickness as to slide in said barrel ot'` which lock 4a) has formed in it.

plays in a recess 153v formed in a transverse locking plate 154. In Fig. 4 the normal position of the lock barrel and said locking plate is shown, whereas in Fig. 4b the .position of the parts is shown when Lthe lock barrel has' been rotated by the key to carry the stud Y152 through an angle of 180 degrecsy whereupon. the stud acts upon the walls of the recess 153 and throws the locking plate 154 to the left, this displaced position being shown in Fig. 4b. lThis locking plate 154 extends across the entire keyboard of the machine and is formed with recesses through which the various keysmay pass, and on the upper side of the plate is an oset 155 which projects into a recess of the same shape formed in a similar locking plate 156;r lhere is asimilar locking plate 156 tor each of the rows ot keys across the machine and'it will he seen plainly from Fig. 4 that these plates are all connected to move in unison by the series of offsets 155 whereby all ot the plates are locked together.` As shown in Fig. 4c the Shanks of the keys are formed with notches 157 cut diagonally across between two adjacent surthe outline of this notch ein shown in dotted lines upon the sections o? the keys in Fig. 4. The bank of clerks numeral keys are however not formed with any such notches, as will be observed in Fig. 4, whereas all of the amo-unt'keys and the-three special transaction keys have such notches, and the totalizing key uhas such a notch upon'its lower The plates 154 and 156 notches and the recesses through which the keys pass are, as regards the three special transaction keys and amount keys, of such shape as shown in Fig. depressing transaction keys when. the plates are all in their normal position shifted to the right; but when the plate 154 is shifted to the lett in the position shown in Fig. 4b as just described, and all of the other plates 156 are likewise shifted to the left by reason of the 4, permitting the osets 155, the plates are then drawn so that their edges now engage with the diagonal notches 157 of all of the amount keys and the three special transaction keys and thereby securely pression. Upon such movement to the lett,

however, of the lowermost platel, it will be obvious that thismovement is to withdraw the edge of the plate from engagement with the diagonal notch formed in the lower left hand corner of the totalizing key 33, thereby unlocking said key, the key being normally locked when the plate stands in itsfextreme right-hand position. This shifting of the lower plate 156 to the left otA course requires that the recess through which the totahzmg key passes should'be suicient of any amount key or the special lock all of said keys from desuflicient to permit this movement, that is, through the medium of a small space such as 158 between the right-hand side of the key and the edge of the plate so as to permit the necessary shift-ing of the plate to withdraw the latter from the diagonal notch; and likewise it will be observed that there are similar spaces 158 to the right of all the clerks numeral keys 31 and this permits the shiftlng of the plates as far as the clerks numeral keys are concerned and since there are no diagonal notches for these keys the keys still remain operative, the recess through which their shanks pass being simply larger longitudinally to allow for the necessary play of the plates, and thus the clerks numeral keys are always unlocked so that they may be operated either for.` ordinary transactions or for the printing of the totals.

It will be seen that the operation of the manipulative device or key barrel 1.50 serves to control the operativeness of the amount and special transaction keys and the special totalizing key, and when the parts are in normal position shown in Fig. 4 all of the keys are operative except the totalizing key which is locked, and when the key barrel 150 is adjusted to the position shown in Fig. 4b, all of the special transaction and the amount keysare locked, while the totalizing key is unlocked. 'This same shifting of the plate 154 by means of the key barrel 150 also serves to adjust certain other parts as will now be described. Straddling a pin 160 formed on the plate 154 is a lever 161 pivoted at 162 and carrying at its upper end a pm 163 which projects into a` groove 164 formed in a collar 165 mounted upon a laterally shifting shaft 166. To the rear of this shaft 166 is another slightly larger shaft 167 (see Fig. 2) upon which the aforesaid totalizingv wheels 19.2 are mounted. In Fig. 11 this shaft 166 is shown broken away so as to reveal the rear shaft 167 carrying the counter wheels. Fast upon. the rear shaft 167 is a disk 168 which projects into a second groove formed in the aforesaid collar 165, so that when said collar is shifted laterally the disk 168 and its shaft 167 will. like wise be shifted to the right. Extending downward from the shaft 166 are arms 169 (see Figs. 1, 2 and 4) the lower ends of these arms having mounted therein a transverse rod 170 which stands in front of the aforesaid shaft 53 (see Fig. 4). This shaft 170 carries a second series of coupling pinions -171, which front line of pinions are shifted laterally to the' right' (see Fig. 4) when the shaft 166 is shifted to the right. It will be plain that this shifting movement takes place when the plate 151 is shifted to the left in the manner n'cviously described, in which case the movement of the lower end of the lever 161 to the left rocks the upper end thereof to the right and thereupon carries thecollar 165, shaft 166, shaft 167 and shaft 170 all to the right, thus carrying the front line/of pinions 171 to the right far enough to cause said pinions to engage bo'th the gears 52 and the totalizer operating gears 120, these pinions 171 being sutl'iciently wide for this purpose. lVhen the parts are in this position it will be seen that ythe totalizer wheels are in effect coupled up to the operating elements 50 through the means of the front line of idle pinions 171, and this is the position which they assume for the purpose of totalization in the manner to be now described.

The totalizing key itself will neXt be described. This key comprises an outer tube 180 (see Fig. 5) which tube is square in crosssection and. contains within it the round shank 181 to the outer end of which is made fast the knurled knob of the key 33. The square tube 180 is arranged to be depressed against the tension of a spring 182, but the I knurled knob carrying the shank 181 may be rotated through an angle of degrees so that a pin 183 formed on the inner end of said shank may assume either a vertical orV a horizontal position. Just above this total key is a false key having a shank 181 spring pressed outward by means of a spring 185 and provided with a downwardly projecting lug 186 which the pin 188 is arrangedrto strike against when the key 33 is rotated so as to cause the pin 183 to assume the vertical position, and thus it will be noticed that when the key is in such position, as shown in Fig. 9, the depression of the totalizing key 33 will carry inward both the tube 180 and the shank 181, and consequently the pin 183 striking the lug 186 also deprcsses -the false key 184. stationary V-shaped and double beveled projection 187 (see Figs. 5 and 5a) causes the shank 181 to be positively rotated either to the horizontal or to'the vertical position upon the depression of a key, according as the pin 183 strikes either the upper or the lower side of said projection 187. so Ithat the siank 181 cannot. assume an intermediate p sition but is compelled to be either in vertical or in horizontal position. Extending from the left-hand side of the tube 18() is a pin 12)() (see Fig. 5a) which extends far enough to project over three detent plates, the right-hand one of which is the detent plate 140 which has previously been described and the purpose of the other two of which will be described later. and projecting still further to the left from the pin 190 is a smaller pin 191 which projects over two other plates, one of which is the stepped operating element v50a (shown in Fig. 13 and previously described), and the other of which is a turn-to-zero segment which is presently to be described.

Referring to Fig. 9 it will be seen that there is pivoted to the transverse shaft 49 a pin the segment 220 the teeth on the upper end of which mesh with the gear wheel 221 which turns loosely upon the aforesaid shaft and meshes` with the pinion 222 fast upon the aforesaid shaft 167 which carries the various registering wheels. `lhis segment is normally spring drawn rearward by means of a spring 223, and the rearward movement is limited by the shoulder 7 5 striking against the previously described trans'- ver'se restoring shaft 64. This segment 220 as shown in ld ig. 5 is adjacent to and to the right of the aforesaid operating element 50a which is used for setting the type wheels for the special transaction and totalizing keys. irojecting from the righthand side of the segment 220 and at the upper end thereof is 22-l, (Fig. 9) which extends laterally to be engaged by the nose'225 (Fig. 7) of a (letent plate 226, which plate as shown in ifig. 5a is the second plate from the right being adjacent to the previously described plate 140. rl`he upper end of this plate is formed with notches 227 into which the pins L18 of the special keys 32 may operate without affecting the plate, and at the lower end the plate is formed with a notch 228 having aV beveled surface 229 which is arranged to be struck by the aforesaid pin 190 which projects from the shank ofthe totalizing key, so that when the totalizing key is depressed the pin`190 will strike the bevel surface 229 and pull the detent plate 226 downward against spring tension and thereby withdraw the nose 225 from engagement with the pin 2211 and permit the spring 223 to pull the segment 220 rearward until its shoulder strikes ythe restoring bar 64. If the spring should fail to work the pin 191 will strike the forward `edge of the segment 220 and positively force the segment rearward. The purpose of this rearward movement of the segment 220 is to reset the totalizer wheels to zero for the purpose of printing the totals, and this zero setting mechanism will-.now be described. The totalizer shaft 167 carrying the various wheels 122 is formed with a series of collars having lugs 230 projecting therefrom (see Figs. 2a` and 4.). These lugs 230 are arranged to coperate with pins 231 fast upon the various registering wheels, but the lugs 23() are normally out of alinement with said pins and are only brought into alinement upon the shifting of said shaft in the manner previously set forth. t 'will be remembered that this shifting' takes place by the adjustment of the manipulative device or key barrel 150 preparatory to the operation of the totalizing key, and when such shifting has taken place and the lugs 230 are brought into lateral alinement with the pins '231, the totalizing key when then depressed will cause the retraction of the segment 220 in the manner explained, and therefore will f seen that there is never any 'upper 4cause the rotation of the shaft 167 by means of the pinions 221 and 222, and the arrangement of the parts is such that the shaft 167 will be given almost a complete reverse rotationso as to pick up all of the totalizing wheels and turn them reversely to zero, thereby of course giving them the samel extent of` rotation, individually as had been previously registered l upon them, method of returning to zero being well known in the art. IThe position of the totalizing wheels shown in Fig- 2EL is that of the nine position, the transfer pin 200 being just ready to trip the transfer tripping pawl 201 on the continued movement of the totalthis.

iter wheel, and if the totalizer is now reset to zero in the manner described, the rotation of the shaft 167 in the direction reversely to that of the movement of registration of the totalizer wheels, will rotate each totalizer wheel so as to bring the tripping pins 2C() to a position on the upper side o t e `forward extending noses 232 of the tripping pawls 201, and the action of the pins against these noses is such as to act directly toward the pivotal center of the tripping pawls, so that the latter cannot be rocked backward'by the pressure of the pins 200 against them, and in this manner the tripping `pawls act as a positive stop for the resetting movement of the totalizer wheels, the counter wheels being in zero position when the pins 200 are brought against thel side of the projecting noses 232 of Thus it will be tripping of the transfer tripping pawls upon the operation of the resetting to zero of the totalizer. The connections for setting up the printing wheels for printing totals upon this resetting of the counter to zero wil-l be described later, but' iirst the description of the totalizing key and its connecting mechanism will be completed. The aforesaidpin 190 (see Fig. 5a) projecting from the side of the key shank or tube 180 of the totalizing key is so flattened on one side as shown in Figs. 7 & 8 as to coperate with a full-stroke device comprising ratchet teeth 240 formed on the wall of a notch 241 formed in the lower end of a detent plate 242 which plate as shown in Fig. 5a is the middle platel of the five plates coperating with the totalizupper the tripping pawls 201.

ing key. The upper end of this plate 242 Y the aforseaid ratchet teeth 240 serve as al full-stroke device to 'compel the complete depression of thekey whenit has once been pin 250 is so situatedl as to strike against the scribed how the shoulders 255 and 256 are so arranged rela- 191 actingl against the shoulder 256 moves tions to be -in the throwout counter detent plate 1-10` so started; thus-this late 242 acts as an ordinary'- detent latcli plate for the vspecial transaction key and for the' totalizing key .and also acts as a full-stroke device for the' *o talizing key. v i

All of the detent plates 140 (Fig. 6), 226 V(Fig. 7) and 242 '(Fig. 8) are suitably spring drawn to' normal position and arel connected with the detent releasing means heretofore referred to in connection with the amount keys and explained indetail in the aforesaid application. The aforesaid false key 184 (see Fig. 5") also has projecting laterally from it an operating pin 250. This pin as shown in Figf coperates with the beveled portion 251 of a slot 252 formed will also carry inward the false key in the ,.mannn: already explained, and -it is upon *eheh ,potion of the totalizing key that the` niachirreis prepared to print the final totals and consequently the designation is placed upon the key itself to show that this is t-he position of printing the nal totals, this designation being if desired simply the letter T and the special printing wheel also bei-ng set by means of this inward movement of the false key 184 to print a vcorresponding designation T to `denote that the tot-al is the final total. Whereas if thethe pin 183 assumes a horizontal position, the false key will obviously not be depressed when the totalizing key is depressed, and

that when this false key is depressed the totalizer will be thrown out of operation in just the same manner in which the special keys 32 throw the totalizer outvof operation, this utilization of the throwout mechanism in connection with the depression of the false key beingr necessary in the operation of printing` the final totals as will be later explained. The pin 250 has no effect uponv the other detent plates 226 and 242 owing to the extra width of the notches 253 and 254 `formed respectively in these plates as shown in Figs. 7 and 8. The pin 250 however does` cooperate with the operating element shown in detail in Fig; 13, for the purpose of setting thespecial printing wheel. The

shoulder 255 `formed on'the lower end of the operating elemeiit 50, and the pin 191 (see Figs. 2 and 5)' is arranged to strikel the shoulder 256 Fig. 13 formed on the operatthe pin 191 acting upon the shoulder 256 of the operating element 50simply sets the said element to cause the printing of a different character as` already explained, to denote che printing of a sub-total, this character being for example,. S, to denote the subtotal. The difference of operation above referred to` that is, whether the machine should print the final or the sub-total, involves simply the 'use' of this throwout totalize-r mechanism which has been previously described and this operation will now be explained. It has already been explained iti-connection with Fig. 4vhowthe revolution ofthe lcck barrel 150 turns the lever 161 and shifts tothe right the shafts 166 and 167 and also the shaft 170 carrying the front line cf idle pinions 171 so as'to couple together 'the total'izcr operating pinions 120 and the companion pinions 52. When this has been done 'the resetting of the totalizer wheels ing element 50* adjacent to but lower than the shoulder 255." It has already been despecial transaction.n keys act against this operating element 50 to set the same differential distances for the purpose of setting the special type wheel to print the special designations, and these two tively to the pins 250 and 191 that the pin the operatlng element 50 one step farther than the lowest of the three special transaction keys whereas the pin 250 acting against the shoulder 255.moves the operating element 5()l still one step farther than the same is moved by the pin 191; .conseto zero in the manner already explained results in turning the totalizer operating pinions 120 to the same extent and thereby through the idle pinions 171 results in turning the pinions 52 and consequently setting all' of the registering segments 50 to differential positions corresponding exactly to the amounts which have been set up upon the 'respective totalizer wheels in just the same manner as if the operator were to de'- press. keys to the amount represented by what. has already been registered upon the totalizer wheels, and when depressed, the registering segments 50 would be set differentially thereby. These registering Segments 50 now having been set by this resetting to zero of the counter, the machine quently this enables two different designaprinted according to whether the false key carrying the pin 250 is depressed or not. This false key, as has been described will always be depressed together with the regular totalizing key whenever the totalizing key is adjusted or rotated to its position in which the pin 183 stands in vertical position in the path of the lug 186 projecting from the false key, so that upon the depressing of the totalizing key the pm 183 is row operated in the ordinary manner.

By the initial revolution of the lower op- -erating shaft 40, a disk 260 (Fig. 2) fast thereon and provided with a box cam 261 actsuoon an anti-friction roller 262 formed on the lower end of a throwout bar 263 which straddles the shaft 40 and at its upper end is pivoted to the shaft 170 which carries the previouslyy described front llne of idle pinions 171. It will be seen that by totalizing key is adjusted toits other position in which the shapeof this box cam that the throwout bar 263"is immediately forced upward upon the first part of the operation of the machine,

and the entlre frontline of idle pinions 171 5 is carried out of .engagement with their respective pairs otgears 53 and 120. Thus the front line of pinions now havlng been thrown out of mesh in this manner, the re f storing bar G4 now comes into operation in the manner already explainedl` and the registering segments 50 are all restored to normal position just as they are upon the ordinary operation of the machine, and the bacll:A

corresponding degree of movement being 1 imparted to the totalizer wheels whereby the latter are set back to the original amounts which had been accumulated thereon; but the amount printing wheels are of course as will readily be understood set to print the amounts exactly correspondingto these totals which have in effect been set up on the registering segments 50 .and thus a printed record of this total will be secured upon this' operation of the machine, and the total will nevertheless'be retained upon the totalizer,

so ,that this total amount can. be carried for- I ward and havethe succeeding registrations added to it, this being known as a sub-tota vl. This retaining of the accumulated amounts upon the totalizer depends -upon the back. line of the idleI pinions being thrown into mesh with the companion gears 53 and. 120

upon the initial operation of the .machine Now however when the totalizing key is ad justed to the so-called final total position in which the pin 183 assumes a vertical position to cause the depression of the Jfalse key 184 when the totalizing key is depressed, the pin 250 of the false key acts upon the bevel portion `251 (see Fig. 6) of the notch 252 of the plate 140 and moves said plate downward into the position shown in Fig. 6 in which Ythe arms 142 has acted upon the pin 143 to break the connection between the bell crank lever 128 and the lbell crank lever 181 so ast to prevent the back line of pinions 123 from being` thrown into engagement with the aforesaid companion gears in precisely the same manner as these various parts operate 'uponthe ordinaryv process of throwing out the totalizer for the special transaction. Thus when this operation has taken place -by the depression of both the totalizingr key and the false key for the striking of the inal total,

then when the registering segments 5() are restored. to normal position upon the operation of the machine, there is no connection between'the totalizer operating pinions and their companion pinions 52, so that the to'- taliz'er Wheels remain restored to zero after they have beenreset to zero as a preliminary procedure to the striking of the final total; but of course the print-ing wheels are nevers theless set to differential to print this inal total. That is upon the printing of the total, 70 the final total or the sub-total is printed according to whether the throwout mechanism for the totalizer is or is not operated, in one case the totalizer being retained in its zero position to which it has been reset by the operation of the totalizing key, and in the other case the totalizer being restored to position tol retain the previously accumulated amounts. Upon this operation of the machine for printing the totals the restoring bar 64 acts .against the shoulder 75 of the turn to zero segment 220 (see Fig. 9) and likewise restores said segment to normal position where its pin 224 is again engaged by the nose 225 of the detent plate 226 upon the release of said plate and the release ofl the depressed keys which takes place at the initial operation of the machine as already referred to. This restoration of the turn to zero segment 220 of course revolves the totalizer shaft 167 in such manner as to carry the turn to zero lugs 230 back to normal position so as to permit the operation of the totali'zer wheels back to their previously accumulated amounts during' the operation 95 of the machine, when thc sub-total 1s printed; and it will be observed that the-shaft 16T practically rota-tes with the tota-lizer wheels during such operation, but of course,

no totalizer whee could be turned al greater extent than nine units, in which case its turn to zero pin will of course simply `follow around with the turn to zero lug 230 carried by the shaft 167.

Paper feed mechanism/.#The general construction and situation of the printing mechanism for securing the printed record both on the detail strip .and check is shown in Fig;'3,but this mechanism is described in detail `in said co-pending application and will only be described herein to an extent Y sufficient to make clear certain i1nprovements connected with the feed mechanism and the mechanism for inking the inking rollers for the check strip.

' The detail strip 280 (see Figf) is 1nounted-upon a carriage 281 `which is arranged to slide laterally for the purpose of printing Athe amounts of the special transactions in a separate column. The strip 1s fed Jfrom a 120` 'storage roller 282 and is'vwound upon a winding roller 288 being led over an impression roller 284 pivoted at the forward end of the frame 281. The frame' 281 has formed upon its outer side as shown in'Fig. 10 a collar 125 285, and by means of this collar the frame 281 is spiined to a shaft 286, the spline groove 287 being shown in Fig. 10, and the purpose of the spline being to permit the lateral shifting of the frame 281 carrying rear cf the rock shaft 286 is the lateral shifting shaft 43 previously described which shaft is so connected with the detail strip frame 281 as to shift the detail strip to print `the special transactions in a separate column as will be later described. Upon the rotation of the shaft 38, the arm288 is rocked and thereby the shaft 286 is rocked and the forward end of the frame 281 is carried downward to bring the impression roller 284 against the type wheels 107 (see Fig. 3), and during such downward'movement of the frame, the detail strip is fed by means of a feed pawl 292 shown in detail in Fig. 10, this feed pawl being suitably pivoted to the main frame of' the machine and springpressed into engagement with a feed ratchet 293 fast upon the winding roller 283. This feed -pawl is made wide enough to engage said ratchet wheel 293 during the entire ex-l tent of shifting movement of the strip car-r riage. For the purpose of shifting the carriage, the aforesaid shaft 43 has formed upon its left-hand end (see Fig. 10) a disk 420 which projects into a groove 421 formed in the collar 285 which is fast to the detail strip frame 281, and thus the'frame 281 may rock independently of the disk 420 upon the operation of the printer, and the shaft 43 with the disk 420 may rotate independently of the frame 281, but when the shaft 43 is shifted laterally in the manner to be presently described, the disk 420 acts upon the collar 285 to slide the entire frame 281 laterally upon its shaft 286 so that the widened detail strip will now be shifted and the relatively stationaryset of type Wheels will of course print in a different column upon the detail strip, the spline on the shaft 286 permitting this lateral movement of the frame 281 andy at the same time makingpossible the rocking of the shaft for effecting the rinting. This lateral shifting of the shaft 4- is effected by the'operation of the machine itself upon the depression of any one of the specialv transaction keys 32'. As shown in Fig. 2 there is pivoted upon the rock shaft 49 an upwardly extending lever 423 at the upper end of which is pivoted a horizontal link 424 which extends rearwardly to connectpivotally with a rocking frame 425 (see also Fig. 10) comprising a collar which is journaled upon the rock shaft 286, this frame carryingan upwardly extending arm 426 and a downwardly extending arm 427, which arms project into proximity with the shaft 43 and carry pins 428 and 429 respectively, the pin 428 being arranged to engage a spiral groove 430 formed in a collar 431 fast to the' shaft 32, and the pin 429 being arranged to engage a spiral groove 432 formed in a collar 433 also fast to the shaft 43. In the normal position of the machine ithe lower piu 429 stands opposite the space 434 between the two collars 431 and 433. l

By referring to Fig. 2 it will be'seen that when any one of the three special transaction keys 32 is depressed, its pin 48 will strike the lever 423 and force the latter rearward, thereby forcing the link 424 rearward, and

thus the frame 425 will be rocked so as tol carry the pin 428 into'engagement with its spiral groove 430, also rocking the lower pm 429 out from between the two collars 431 and 433. Now upon the rotation of the shaft 43 upon the operation of the machine7 the spiral groove 430 acting upon the pin 428 causes the entire shaft 43 to be shifted laterally thereby shifting thev detail strip frame 281 to effect the printing-in a differentcolumn. To effect this shifting, ythe rock frame 425 is held fixed in place by means of two collars 436 fast to, the shaft 286 on either side of the frame 425. next operation of the machine a special key 32 is again depressed, no shiftingefect is' produced upon the shaft 423, for the extent of the revious shifting has been such as to carry tlie space between the two collars 431 and 433 opposite the upper pin 428 and hence the pin 428 when again carried downward simply enters this space between the collars and upon the rotation of the shaft 43 no shifting effect of the carriage isproduced but the carriage is locked in position because of the engagement of the pin 428 in said space between the collars. Ifhowever upon the next operation of the machine no special key is depressed but an ordinary cash transaction' is recorded the lever 423 remains in' normal position andtherefore the lower pin 429 now rests in its spiral groove 432, the direction of which spiral is the reverse to that of the spiral'430 so that upon the revolution of the shaft v43 the spiral groove 432 acts upon the pin 429 to restore the shaft 43 and the Adetail strip printing frame 281 to normal position for the cash transactions', the shifting in each case preceding the printing movement. Thus it will be observed that the carriage is shifted only when it is necessary from one class of transactions to another. And the total amounts are printed in the same column with cash transactions since the total key has no effect upon the lever 423 to shift the detail strip carriage. A suitable spring retains the lever 423 in normal forward position, but since these special keys are releasedA on the initial part' of 'the operation of the machine, and arm 440` (see Fig. 2) is mounted upon thecollar which carriesthe If upon the`
